To all whom it may concern.

Be it known that I, OSCAR PETER BECK, a subject of the Emperor of Germany, at present residing in the city of New York, county and State of New York, United States of America, have invented certain new and useful Improvements in Apparatus for Making Half-Stuff from Peat-Turf, of which the following is a full, clear, and exact specification.

My invention relates to machines for the reduction of peat turf, whereby the said peat,

is prepared as a paper or paper-board stock, and particularly to that type of machine wherein the raw peat turf is spread upon a carrier and there subjected to the action of stampers, so as to reduce the whole to a fibrous mass without removing the vegetable matter, and my invention consists in various improvements in the details of construction of such machine hereinafter more particularly pointed out, whereby the construction of said machine is simplified, less power is consumed in the machine, and its operation is improved.

My invention also relates to an improved form of stamper used in connection with the said machine, whereby the more effectual reduction of the peat turf is accomplished.

My improved machine is fully illustrated in the accompanying drawings, wherein Figure 1 is an elevation of said machine with part thereof broken away for clearness. Fig. 2 is a horizontal plan view of the machine. Fig. 3 is a vertical sectional elevation of the stamper actuating mechanism. Figs. 4 and. 5 are similar views showing details of the same mechanism. Fig. 6 is a detail plan view of the mechanism illustrated in Fig. 3, the stampers being omitted; and Figs. 7 and S are sectional elevations in detail of a modified form of the stamper actuating devices.

My improved machine is mounted upon a base 1, to which are attached upwardly extending posts or standards 2, 3, 4, 5, 6, 7. Upon the upper part of the inwardly extending bases of these posts are suitably j ournaled a series of rollers 8, upon which revolves the annular peat carrier 9, the sides of which extend upwardly, forming walls. Upon the inner side of the bottom of this carrier is a bed plate 10, which may be made of stone, iron, or other suitable rigid material, and which carries the evenly spread bed of peat turf 11, which is to be treated.

The power to operate the machine is obtained through fast and loose pulleys 12, 13, mounted upon driving shaft 14, which is connected by pinion 15, with gear 16, fixed upon the driving shaft 17 which is journaled in posts 2, 3, 4, 5. Fixed upon the same shaft 17, is a beveled gear 18, in mesh with a series of similar gears 19, and also fixed upon the said shaft 17 is another similar beveled gear 20, in mesh with another series of similar gears 21. Gears 19 are mounted upon radial operating shafts 22, and upon carrier driving shaft 23, and gears 21 are mounted upon radial operating shafts 24. Each of these operating shafts 22 and 24 are journaled in posts similar to posts 4 and 5, which are attached to the base plate 1, and project upwarclly from it. Shaft 23 is journaled in posts 6 and 7, and has near its outer end a pinion 25, meshing with gear 26, mounted upon shaft 27, journaled in arms 28, projecting from the post 6. Fixed upon shaft 27 is a beveled gear 28 meshing with beveled gear 29, upon shaft 30, which at its lower end carries pinion 31, meshing with a rack 32, upon the exterior lower surface of the carrier 9, by which the said carrier is rotated.

As illustrated, the machine contains nine sets of stampers, each set comprising four stampers, and situated, two upon each side of the operating shafts. The shaft 17 operates one set of stampers at each end, and the other sets of stampers are operated by countershafts 22 and 24.

Mounted in each pair of posts 2, 3, are two supporting rods or shafts 33, 34, arranged vertically above and below shaft 17 and carrying loosely journaled thereon rocking levers 35, 36, which at their outer ends are pivotally secured to collars 37, 38, which are fixed upon the stem 39 of the stamp 40. Rocking levers 35 and 36 are connected by connecting rod 4]., to which, at about midway of its length, is attached a tappet 42, which is lifted by cams 43, of which two are illustrated, fixed upon opposite sides of shaft 17.

As shown in the plan view, Fig. 6, rock lever 35, is bifurcated. at its outer end, where it embraces the stem 39, and likewise at its inner end, and connecting rod 41 is likewise made in two parts connected by the outwardly extending arms of tappet 42, and by headed bolt 44 and nut to the rock lever 35,

' the said shafts.

likewise projects a short distance from the' opposite side of shaft 34, and terminates in a stud or bolt 50, which passes through the bifurcated ends of said rocking lever 48, and the outer ends of which also enter a slot 51, in the lower end of a bifurcated connecting rod 52, the lower slotted ends of which embrace the bifurcated ends of said rock lever 48, and are held in place by a nut and head upon the bolt 50. The said connecting rod 52 above the operating shaft has a bend at 53, which causes it to pass to the opposite side of the operating shaft, where it is pivotally connected to rock lever 45 by boltand nuts. Situated midway upon the connecting rod 52, is a tappet 54, in position to be engaged by cams or lugs 55, fixed upon opposite sides of the operating shaft, 17.

In the form illustrated in Figs. 3, 4, and 5, the stamps 40 are raised and then allowed to drop by their own weight. I have shown, however, in Figs. 7 and 8, a modified form in which adjustable weights are employed for the purpose of increasing the quickness of action of the stamper, and adding to the force of the blow.

In the form shown in Fig. 7, bifurcated rock levers 56, 57 are journaled upon shafts 33, 34, and their outer ends are pivotally secured to collars 59, 60, which are fixed upon the stem 61 of the stamp 40. The rock levers 56, 57, are connected by bifurcated connecting rod 62, which is pivotally secured to them as by bolts, and to which is attached tappet 63, operated by cams 43, 44, fixed upon the operating shaft.

Stem 61 is made hollow, and has a central chamber 64, in which may be placed the desired quantity of weighting material, as for instance, shot.

In the form illustrated in Fig. 8, the shafts 33, 34 carry rock levers 65, 66, which are bifurcated, and project "from one side of the said shafts a short distance, terminating in pivots or bolts, by which the said levers are connected to connecting rod 67, to which is attached tappet 68, operated by cams 43, 44, which are fixed upon the operating shaft. The opposite ends of the levers 65, 66 are pivoted to collars 69, 70, which are fixed upon the stem 71 of the stamp 40. Said stem has fixed upon it a supporting collar 72, above which is a semi-cylindrical shell 73, which as shown is open at the top, and has a base 74, and is designed to receive weights 75. These weights have radial slots equal in width to the diameter of the stem 71, by which they may be inserted in the shell 7 3, and after insertion may be partly turned around and will be securely held in place. Any number 'of said weights may be employed, thus securing the desired weight upon the stamper 40.

Figs. 7 and 8 illustrate two forms of weighted stamper, each of which, as shown, is adapted to operate upon the same side of the shafts 33, 34. The opposite sets of stampers may be of the form illustrated in Fig. 4, and actuated by the devices there shown, the stamp stem 39, however, in such case being weighted as illustrated in either Fig. 7 or 8.

The form of stamper illustrated is regarded as highly desirable, and the same forms part of my present invention. The said stamper may be rectangular in area, or of other desired shape. The lower surface, however, which contacts with the peat, I make in a curved or semi-circular form, whereby the same has the highly advantageous property of easily penetrating the mass of peat, and reduces or draws out the fibers in a satisfactory manner. The said stampers are shown in end view in Fig. 3, from which it will appear that the bearing surface thereof is curved in cross section, or in the direction of movement of the peat, and, as shown in Fig. 1, the said stampers are not curved longitudinally or in the direction transverse to the movement of said peat. I prefer to make the said stampers of wood, as this material has been found to be highly satisfactory for this purpose. Other material, however, may be employed.

The operation of my device is as follows: A layer of peat turf having been spread upon the bed plate 10, of the carrier 9, power will be applied to the said machine and the carrier rotated through the train of gearing connected with shaft 23. Simultaneously, beveled gears 19 and 21 will be set in motion through the gears 18, 20, upon operating shaft 17, and lugs 43 will, through tappet 42, raise their connected stamper 40, which will drop as soon as the said lug passes tappet 42. As soon as this occurs lug 55 will engage tappet 54, and the opposite set of arms will cause their connected stamper 40 to operate. By this means, through the employment of a single operating shaft, which rotates con tinuously in one direction, I cause oppositely disposed stampers to alternately stamp the peat turf. I have illustrated two stampers upon each side of each shaft. They will be constructed and operated in the same manner. More than two' may be employed if desired, for this purpose.

It is obvious that modifications and changes in the form and connections of the various elements shown may be made without departing from the spirit of my invention, but
